Photosynthesis in thick cyanobacterial films: a comparison of annual and perennial antarctic mat communities

  title={Photosynthesis in thick cyanobacterial films: a comparison of annual and perennial antarctic mat communities},
  author={Ian Hawes},
Annual and perennial cyanobacterial mats from streams on Signy Island, Antarctica, show similar areal concentrations of chlorophyll-a and areal rates of photosynthesis. Maximum rates of photosynthesis were temperature dependant over the range 0–14 C, with a Q10 of approximately 2.5. Rates of photosynthesis per unit chlorophyll-a were comparable to other Antarctic mat communities but low compared to phytoplankton from upstream lakes. Areal rates of photosynthesis were however much higher than… CONTINUE READING
